Saab Key Programming

Saab cars made since 1994 come with an immobilizer system built on coded keys. A new transponder is required to allow the inclusion of an additional key, and special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

The issue is that this can be very expensive. It is recommended to always have a spare set of keys in your possession.

Transponder key

The transponder key is a key with an electronic chip that sends a signal to the car when it is inserted into the ignition. The car will then check the signal to determine if it matches the one on the key. If the signals are in sync then the car will be able to open and start. This is a fantastic way to guard your car against theft.

Transponder keys are a favored feature in cars, but you should be aware they're not as secure as traditional keys made of metal. While the metal portion of a traditional key could be cut and copied but a transponder key is protected by an electronic chip. This chip contains a unique code that is embedded into the car's computer to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. But, it's only able to do this if your key fob has a non-modified chip that has been programmed to match the original. The car will not start in the event that the key has not been programmed to match.

It's crucial to ensure that you have an extra key for your saab ignition key replacement (Read More Here). This is especially true for those who live in a rural region where there are a lot of car burglars. The good news is that it's possible to obtain a replacement key for your Saab without needing to visit an auto dealership and pay the high costs that they ask. You can get the replacement key on the spot for less than half the cost you would pay at an auto dealer.

Wired key

saab 93 replacement key cars typically come with two keys when they're new. If you only own one, you need to purchase an extra key as soon as you can. This is because if it's lost saab key and the car needs a new CIM and the locking cylinders replaced. This can be costly especially if purchasing a used vehicle.

The next step is to connect the row and columns wires to your microcontroller. This is the most laborious component of the project and will require a lot of soldering. There isn't a standard method to do it, but you should plan how to route and solder each column and row. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered together then it's time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins from current, thus preventing them from getting shorted. A diode can only allow the current to flow in a single direction, and it also has a a black band visual indicator that indicates the direction in which current will flow.

Some of the tools you can find at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- can assist customers at the shop or DIY customers in certain instances create replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into OBD ports and guide the user through each step and make the process more straightforward than replacing the car's computer.

Jump starting the battery

Most people keep a few sets of jumper cables in their trunks to use in an emergency however, jumping a battery in newer vehicles might not be the best option. These vehicles have many digital and electronic devices that communicate with each other. A surge in voltage when a battery is hooked up to another can fry these components and leave your vehicle undriveable.

Start the vehicle you are using and let it run for about two minutes before connecting the cables to the non-working one. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clean unpainted metal surface underneath the hood of the damaged vehicle. The engine block is a great choice. Do not connect the black cable to the negative terminal of the dead battery, as it could ignite an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, start the vehicle that has been disabled and let it run for approximately five minutes before you disconnect the cables in reverse order. The battery in the saab 900 key 9-3 will charge while you drive. It takes a while for it to return to its original state. You should invest in an additional key fob when you can. Replacing the one that works requires the installation and programming of a new computer chip.

Replacement Case

Saab owners usually only have one car key, and if it is lost, they'll be charged. It's costly to add a key and requires replacing the CIM or TWICE in the case of older models. It is best to have a spare key in the event of theft or other disaster, and the best way is to buy an extra key as soon as you can. Even it's "new", it won't work.

The dealer will charge you the most expensive dollar if you only have one working key. However, we can reset and re-program your computer's EEPROM in order to prepare it to accept an alternative key without replacing the whole system. This can save you a significant amount of money. It's also less expensive than waiting until you lose your sole key.
